hi Vaibhav,

thanks for the links.

the calculation of

range = rangeBin2Meters; %rangeBin2Meters is an array from 0:range_resolution_bin:maxRange of the chirp

is still not very clear to me. where do I find variables 'range_resolution_bin' and 'maxRange'. I am looking into the Automated Doors and Gates demo in the mmwave_industrial_toolbox_4_4_1

The variable close to 'range_resolution_bin' in my workspace is Params.dataPath.rangeResolutionMeters but not sure this is correct. Also, I do not know what variable that could relate to 'maxRange.

FYI, I was able to successful get the AzimuthHeatMap into my workspace using the instructions from https://e2e.ti.com/support/sensors/f/1023/t/813923?IWR6843ISK-Range-Azimuth-Heat-Map-How-to-parse-TLV-and-compute-data.

Hello,

In the gui folder of the lab there is a file called calculateChirpParams.m please refer to this to see how these calculations are performed.
